Isn't ATC expecting a standard rate turn if you're IFR? That's what I was taught, at least.
You should put that option back in...
or at least make sure the box is smart enough to follow the AIM, e.g., for holding patterns, the rule is 3 deg/s, OR 30 degrees bank angle, OR 25 degrees bank angle IF a fight director is used.
I'm sure there are other callouts in the AIM for turn rates...
I agree, 30 degrees is excessive at slow speeds.
